Enabling cupsys Web Admin Interface October 13, 2005Posted by Carthik in administration, ubuntu.
If you are trying to get your printing system going, and search for tips and docs on the web, you will find most of the documentation referring to http://localhost:631 as your cupsys administration interface. However, on Ubuntu, this browser-based administrative interface for cupsys is disabled by default. Here’s how to enable it:
Select “System”->”Administration”->”Users and Groups” from the main menu on your desktop.
Select “Show all users” and/or “Show all groups”.
Add the user “cupsys” to the group “shadow” in the “groups” tab.
Restart cupsys by issuing the command:
$sudo /etc/init.d/cupsys restart
IMPORTANT: I don’t know why the web admin interface was disabled in the first place – so please know that it is best to reverse all that you did once by removing the user cupsys from the shadow group,a nd restarting cupsys, once your work with the interface is done. If anyone knows why the web-browser interface was disabled in Ubuntu, please let me know – a lot searching and reading changelogs led me nowhere🙂
